JMS vendor. When you deploy the Web service, it connects to the selected JMS server and subscribes to the JMS queue or topic, so it can receive the messages sent to that destination. Toggle navigation. Important: To see the latest version of the document click here. Messaging middleware has a store-and-forward paradigm and asynchronous message passing, while web services tend to promote a synchronous procedure calling paradigm.
In distributed systems where a lot can go wrong, dealing with things asynchronously tend to focus the mind better to the things you need to do when part of the system is not available or poorly performing and the code needed to deal with that tends to be a lot less complicated. Clustering parts become trivial if you have multiple servers listening on the same queue, parallelism and load balancing is for free in this case. Personally I find JMS much easier to work with and more robust and reliable than web services, but the messaging middleware must support all platforms you want to use.
If all the components who need to talk to each other are under your control, I would give a messaging middleware with a JMS interface serious consideration. If the other party is external then probably Web Services rule, and in that case you could think of a using thin layer to convert the external web service to an internal message passing infrastructure so you still have the most of the advantages. If it is "just slapping an remote API on a webapp" then of course it does not pay either to setup asynch messaging.
I would first go through the documentation in ServiceStack's Authentication Wiki to get a better idea about how ServiceStack's Authentication works. There's a lot of documentation in the wiki, so if you're unsure of something you should refer to that first. It's a community wiki so feel free to expand whats there if you think it can help others. If you're unsure of what something does you should refer to the RequiredRole source code as the master authority as how it works.
RequiredRole is just a Request Filter Attribute which gets run before every service that has the attribute. Because it just calls your session you can override the implementation of session. HasRole if you have a custom session. The Social BootstrapApi project does implement its own CustomSession that it registers here but does not override the HasRole implementation so it uses the built-in implementation in the base AuthUserSession.
The Roles property as well as most other properties on a users Session is populated by the AuthUserRepository that you have specified e. So for a user to have the required role and authorization to pass , it should have this Role added to its UserAuth db row entry.
ServiceStack's AuthFeature includes 2 services for managing users permissions and roles:. These services does require a user with the Admin Role to be already authenticated. You can do this by manually changing a specific users UserAuth. Role column to include the value "Admin". Can you explain further what this "thin layer" would be?
